=Parallax=

*SX
** These were formerly made by Ubicom. The SX die is still manufactured by Ubicom, who send it to Parallax for packaging
** SX-18, 20, 28, 48 and 52 versions (Note that the SX-18 and SX-52 have been discontinued)
** Parallax's SX series is an 8 bit microcontroller which has unusually high speed, up to 75 MHz (75 MIPS), and a high degree of flexibility. Andre LaMothe has proven that the SX-52 can actually be clocked to 80 MHz (80 MIPS) even though the specs say 75 MHz is the maximum. He has used the SX-52 in thousands of XGameStation development computers all running at 80 MHz. Some users have referred to these microcontrollers as PICs on steroids. While Parallax's SX micros are limited in variety, their high speed and additional resources allow programmers to create 'virtual devices', including complete video controllers, as required. Refer to Parallax's Web site for information, as they are the sole distributor of these devices.
